Ten Thousand Worlds System: Anime Guardians of Earth

With rifts to other worlds set to invade in three months, Li Xuan is reborn and awakens the Myriad Worlds Goods System, which lets him exchange for Naruto-style sage arts, One Piece Haki, and Soul Reaper Zanpakuto. But when he reports the impending disaster, everyone dismisses him as a lunatic. Only when a D-rank monster tramples the streets does he carve a way to safety with the Leaf Gale.

The government steps in to cooperate, and Li Xuan builds an exclusive platform for the military, teaches soldiers how to extract chakra, and leads a team through D-rank dungeons. When the System upgrades and unlocks the Sage Body, he forms a squad of sage arts users to face the A+-rank boss, the Arctic Flame Lord. As stable, high-level dungeons emerge around the world and the public celebrates their conquests, Li Xuan realizes they are actually forward bases for an invasion from another world.

The System suddenly reveals the conditions for Level 4: conquer an S-rank dungeon, awaken six billion people, and reach a hundred million A-rank combatants. No S-rank rift has ever been found, and fewer than a thousand A-rank fighters exist. Li Xuan has no choice but to bring these powers to the world at large. From a hundred thousand awakened people to 1.3 billion preparing for war, from fighting alone to forming an international alliance, the war to repel another world with the power of anime has only just begun...
